KANSAS CITY, Mo. — Two federal agencies say there is no evidence that four cases of a rare bacterial infection in babies are related, and there is no need to recall infant formula.

The Food and Drug Administration and the Centers for Disease Control say four infants were sickened by Cronobacter, including one in Missouri and another in Florida who died of the illness. The other two babies, in Illinois and Oklahoma, have recovered.

Several national retailers pulled a batch of powdered infant formula after learning the Missouri child had consumed Enfamil Newborn.

Friday’s report says no Cronobacter bacteria were found in sealed containers of powdered formula.

CDC says Cronobacter is a very rare cause of a severe infection in young infants, and usually occurs in the first days or weeks of life.
